Quality Control

Our production of this high-performance hardener adheres to strict quality management protocols. Every batch is analyzed to ensure consistent reactivity, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as amine value, epoxy equivalent weight (EEW), viscosity, and color are provided to guarantee it meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
